Description

Virtual Network Computing (VNC) is a remote display system which allows youto view a computer's desktop environment not only on the machine where itis running, but from anywhere on the Internet and from a wide variety ofmachine architectures. TigerVNC is a suite of VNC servers and clients.It was discovered that vncviewer could prompt for and send authenticationcredentials to a remote server without first properly validating theserver's X.509 certificate. As vncviewer did not indicate that thecertificate was bad or missing, a man-in-the-middle attacker could use thisflaw to trick a vncviewer client into connecting to a spoofed VNC server,allowing the attacker to obtain the client's credentials. (CVE-2011-1775)All tigervnc users should upgrade to these updated packages, which containa backported patch to correct this issue.
